Schemer is a database schema migration library for Rust that supports directed acyclic graph (DAG) dependencies between migrations. It currently has adapters for the following databases:

• PostgreSQL: schemer-postgres
• SQLite: schemer-rusqlite

Other Rust schema migration libraries to consider if you do not require DAG migration dependencies:

• schemamama (recommended -- this is the basis for Schemer's API)
• dbmigrate
• migrant

Version bumping (including changelog release section versioning) is handled by cargo-release, e.g.:

cargo release --workspace minor
